Agents\' post-9-11 inquiries at libraries raise privacy questions

They say an FBI agent walked into the Carpenter branch of the St. Louis Public Library, asking to see sign-up sheets that detailed the names of patrons who used library computers on Dec. 28 and walked out with the records later that day, with no subpoena or court order.
The request was prompted by a tip from a library patron who had used one of the branch\'s 16 Internet-accessible computers on the same day and at the same time as another patron, who was of Middle Eastern descent.
